I am considering the AD8237 as a strain gauge gain amplifier.
The reason is that the natural offset of the strain gauge is large, about ± 500 mV.
With a general instrumentation amplifier, this offset will saturate the output.
I am thinking about signal gain of about 100 to 200 times.
At this time, I plan to use the DAC to adjust the output common mode.
Is this usage okay?
In the above formula, Vin(max) is very large at 500 mV, so RA becomes large.
RA has a big effect on the gain, but is there any other problem?
I think it is possible in theory, but I would like to know if there is any problem in actually using it in this way.
